From the Black Ops Dept.:

For those of you looking for black straws to make a nifty grid spot, Panera Bread apparently uses them.

Look, I am not condoning any large-scale black straw thefts here. But at least try not to be obvious about it.

And at least buy a bagel or something while you're there.

UPDATE: Apparently Cheesecake Factory uses black straws, too. If you know where to find black straws, or want to see where else others have found them, hit the comments to find out._________________________
